[Alt-photo] Re: GUM - Wash paper after hardening

[Loris Medici]

I don't know, I personally don't like the idea of a separate hardening
bath(*), therefore never used one.

(*) Because:

   - I'm not sure about the stability of large diluted formalin baths,
   - You have to deal with considerably more formalin,
   - It's a two steps process taking more time than I would like to spend.

Good luck with FAEW/SP, it's a very nice paper.

Regards,
Loris.
